大气折射和色散对激光传输的影响

Effect of atmospheric refraction and chromatic dispersion on laser transmission

由于大气折射和色散效应,当用可见光或红外线瞄准目标而用另一波长的激光对目标进行探测或打击时,瞄准路径和激光传输路径是不一样的,瞄准点和激光束之间存在误差。本文建立了大气层折射模型,并给出了在不同仰角时,用可见光(0.55μm)和红外线(4μm)进行瞄准、用CO_2激光器对10 km远的目标进行探测或打击,瞄准点和CO_2激光束之间的距离大小。

Because of the atmospheric refraction and chromatic dispersion, the aiming path and the laser path are different, when the laser wavelength is different from the aiming light wavelength. This paper gave the model of atmospheric refraction and chromatic dispersion, and calculated the error of the aiming point and the laser beam when C02 laser attacks the target 10km distance, which is aimed with visible light and infrared independently.
